Blockchain based identity

Blockchain, the secure distributed ledger technology first created to track bitcoin ownership, has taken on a number of new roles in recent years tracking anything of value from diamonds to real estate deeds to contracts. The blockchain offers the promise of a trusted record that can reduce fraud. Some industry experts say that over the coming years, it could be used to control identity information in a more secure fashion. As we have seen, just last week with the massive Equifax hack , our personal information is highly vulnerable in online databases in their current form. The argument goes that if our identity were on the blockchain, it would give us more control over this information, and with proper applications allow us to present just the minimum amount of information a given party needs to identify us.

Research on Blockchain-Based Identity Authentication Scheme in Social Networks


Blockchain technology represents an important solution for preventing massive data breaches in the future. This article explores two possible ways this solution could manifest, profiling two ventures -- Blockstack and Civic.

From the 3 billion Yahoo email accounts compromised in to the credit and identity data of million Americans stolen from credit bureau Equifax and myriad other attacks massive data breaches have become all too familiar. While cryptocurrencies and cryptocurrency networks such as Bitcoin and Ethereum continue to flood headlines, the future applications of blockchain technology may be what ultimately solve a range of pernicious issues that affect businesses and people alike.

Some have seen a promising future solution to this problem in the rise of blockchain technology. As a recent Toptal Insights article explains, blockchain technology refers to a peer-to-peer distributed, immutable ledger of information. A defining characteristic of this technology is its distributed, peer-to-peer structure, which theoretically obviates the need for intermediaries like Yahoo or Equifax to house data.

With regard to identity protection, some have argued that blockchain technology can potentially eliminate the need for intermediaries and allow individuals total control over their digital identities, while others have suggested that companies can still process personal data but use blockchain technology to access and verify this data without using easily-hacked servers.

This article will explore each of these solutions in greater depth, focusing on one example of each approach. In doing so, we will gain an understanding of the approach each company advances, their challenges, and their relative merits. The internet was originally designed as a peer-to-peer, decentralized web of connections, meaning that any user could communicate and connect with any other user without relying on an intermediary.

Servers can and, as we know, have been hacked, and the concentration of personal data in the hands of a small group of companies increases the risk of these breaches continuing.

A small group of companies gained control over everything from issuing website security certificates to patrolling access to the world wide web to curating individual online identities. This centralization of control allowed these companies to amass huge volumes of personal data, housed on servers, from everyone who uses the internet. These servers can and, as we know, have been hacked, and the concentration of personal data in the hands of a small group of companies increases the risk of these similar breaches occurring in the future.

Blockchain technology provides a potential solution to the problem outlined through enabling people to store data on a blockchain, rather than hackable servers. Information, once stored on a blockchain, is secured cryptographically and cannot be altered or deleted, thus making massive data breaches very difficult, if not theoretically impossible. While storing data on a blockchain as a general, high level solution seems clear, there are multiple theoretical approaches for implementing it.

One strategy is to eliminate the need for intermediaries through enabling individuals to store their identities and data directly on a blockchain that a user carries with him or her everywhere online. Another approach is to allow users to encode their personal data onto a blockchain that can be accessed by third parties. This approach does not eliminate the need for intermediaries entirely, but rather eliminates the need for intermediaries to store sensitive personal data directly on their servers.

Using blockchain technology, Blockstack aims to solve the aforementioned security challenges through eliminating the need for digital intermediaries and allowing individuals to retain full control over their data.

The internet was initially designed using open protocols — communication between computers via the internet was free and not owned by any centralized body. Most of those things basically revolve around security.

As certain applications, such as Google and Facebook, enabled people to establish and communicate individual identity online and gained popularity, the internet became increasingly centralized around a small group of powerful players. This concentration of power has had obvious economic implications and, most relevantly for Blockstack, a profound impact on how personal data is stored, transmitted, and used.

Through its decentralized identity system, domain name system, and storage network, Blockstack aims to give people full ownership over their digital footprint. In doing so, massive centralized data breaches can theoretically be avoided in the future, as there will no longer be a need for third parties to store data or facilitate communication.

Yet a key challenge, as described in the white paper, that Blockstack faces in using blockchain technology is the risk that the blockchain can come under the control of a single entity — in other words, that it can go from being decentralized to centralized.

Scaling the Blockstack network represents another hurdle. Currently, there are nearly 15, developers in the Blockstack community and over 76, domain names have been registered. Blockstack will ultimately need a far larger ecosystem to achieve its stated goal.

While still in its relative infancy, Blockstack presents a potentially revolutionary solution not just to current problems in identity management and security, but to the monopolized power structure of the current internet.

Civic , founded in , advances a different blockchain-based identity management solution. Rather than removing the need for third parties and creating an entirely new internet ecosystem, as Blockstack aims to do, Civic seeks to work within an existing framework and focuses specifically on identity management and security.

Through blockchain technology, Civic enables individuals and companies to verify their identities without having to store this data on centralized, breachable servers. A recent Forbes article explains this process. Civic then cryptographically encrypts this information and stores it on a blockchain. It is never stored on our servers! Civic faces many of the same obstacles as Blockstack: its blockchain could ultimately fail, and its success depends on user adoption.

But which approach holds more promise? Some may prefer the solution proposed by Blockstack, as the hugely ambitious goal of creating an entirely new internet has profound implications well beyond the field of security or identity management. Its approach has the potential to fundamentally redefine the economics of the internet and the way people interact virtually. In eschewing this goal and instead zeroing in on the specific problem of identity management — a complicated, ambitious issue in its own right, but one narrower than creating a new internet — some may argue that Civic has a better chance of successfully accomplishing what it has set out to do.

The growth and development of this space — and the mere fact that these potential solutions exist — should provide those of us concerned with the security of our private data a sense of hope for a better future in identity protection.

The question of which approach will ultimately prove more successful remains unsettled. Still, the growth and development of this space — and the mere fact that these potential solutions exist — should provide those of us concerned with the security of our private data a sense of hope for a better future in identity protection. Blockstack and Civic each offer identity management solutions predicated on using blockchain technology to decentralize and secure personal data.

They also both use tokens their own cryptocurrencies to fuel and incentivize the utilization of their platforms. But as regulators, and entire countries, crack down on trading cryptocurrencies, the full impact on projects such as Blockstack and Civic remains an open question.

The regulatory environment nevertheless remains uncertain, and the possibility that tokens may not be traded as freely in the future looms as a potential risk that should not be ignored for ventures like Blockstack and Civic.

Still, this risk should not hinder the exploration of blockchain-based identity management. It is, of course, important to note that blockchain technology is not a panacea. Indeed, as Ali says in the previously mentioned interview, blockchain technology works very well in some types of applications, and may be wholly inappropriate in others.

Self-sovereign identity SSI solutions implemented on the basis of blockchain technology are seen as alternatives to existing digital identification systems, or even as a foundation of standards for the new global infrastructures for identity management systems. It is argued that 'self-sovereignty' in this context can be understood as the concept of individual control over identity relevant private data, capacity to choose where such data is stored, and the ability to provide it to those who need to validate it. It is also argued that while it might be appealing to operationalise the concept of 'self-sovereignty' in a narrow technical sense, depreciation of moral semantics obscures key challenges and long-term repercussions. Closer attention to the normative substance of the 'sovereignty' concept helps to highlight a range of ethical issues pertaining to the changing nature of human identity in the context of ubiquitous private data collection. Abstract Self-sovereign identity SSI solutions implemented on the basis of blockchain technology are seen as alternatives to existing digital identification systems, or even as a foundation of standards for the new global infrastructures for identity management systems.
